This week’s poll question is: How Many Backups of Your Important Data Do You Have?

Think about those files of yours you care most about and tell us how many places you’ve backed them up. Is it across multiple computers in your house? At work? Several USB sticks? Emailed to yourself? On a DVD at a friend’s house? In the cloud?

So, tell us about your backup solution. What mix of cloud/offsite/local backup do you consider safe for your important files? How does that compare to what you actually do? Let us know in the comments!

Several external hard drives with one for weekly backups, Dropbox for non-sensitive work projects, one backup computer with a copy of the most important stuff. Browser tabs, bookmarks, and passwords are synced online.

I have a local HDD(s) (via PogoPlug) for a complete local backup, plus a full backup to CrashPlan Central for each machine. Additionally, I use the 50G DropBox plan to sync & backup my current working files & dev server (XAMPP).
